 *Release date: xx-xxx-2003*
 
+- Implemented the 'interrupt' extension module, which allows a subthread
+  to raise a KeyboardInterrupt in the main thread.
+
+- Attempting to save the shell raised an error related to saving
+  breakpoints, which are not implemented in the shell
+
+- Provide a correct message when 'exit' or 'quit' are entered at the
+  IDLE command prompt  SF 695861
+
+- Eliminate extra blank line in shell output caused by not flushing
+  stdout when user code ends with an unterminated print. SF 695861
+
+- Moved responsibility for exception formatting (i.e. pruning IDLE internal
+  calls) out of rpc.py into the client and server.
+
 - Exit IDLE cleanly even when doing subprocess I/O
 
 - Handle subprocess interrupt in Windows with an RPC message.  
 
 - Calling Run will restart the subprocess even if user code is running.
+  SF RFE 661321
 
 - Restart the subprocess if it terminates itself. (VPython programs do that)
